IMPROVEMENT IN QOALSHVL.

The Schedule referred to in these Letters Patent and making part of the same I, JAMES F. BREWER, of Plautsville, in the county of Hartford, and State oi'l Connecticut, have invented a new and useful Improvement in Coal-Shovels, of which the following,T is a specification.

, My invention consists in the combination of a sheetmetal pan and a cast-metal shank east onto the pan.

In the accompanying drawings- Figure l is a iiont elevation of my invention, and

Figure 2 is a plan -view of the blank for forming the pan.

The pan or blade A is iii-st hlanked out with a portion of the same cut way, thus forming the recess a, shown in iig. 2.

'lhe pan is formed. iu ordinary swinging-dies, while the recess a liberates the edge of the metal composing the pan A, which would` otherwise be contracted and wrinkled in swaging, whereby I am enabled to swage a verysmooth pan.

As usual'in casting one article onto another, a pattern is made of the form of both of the parts, and its imprint taken in a mold.

'lhe pan A, formed as before described, is placed in the mold, where the` shank B isrcast firmly onto the same, the cast metalilling the aperture or recess a, and extending a short distance over the edge ot' the sheet metal, as indicated by broken lines in iig. 1.

In thevdrawings the shank B is provided with a sockeal), to receive a Wood handle, but the style of handle and the manner of securing thesame vto the shank B are immaterial to my invention.

'Although 4I prefer to cut the aperture or recess a in the form substantially as shown, for the purpose of obtaining a neatly-swaged pan, the aperture may be fmade of any other form which will allow the metalof the 'shank B to cast firmly onto the pan A.

The weakest point in ordinary sheet-metal shovels is the part near the shank, which is generally secured by rivets, which often tear out before the utility of the article is otherwise impaired. I
